Background 

The 2018 Annual Survey of Hospitals is a cooperative survey between the Texas Department of State Health Services (DSHS), the American Hospital Association (AHA), and the Texas Hospital Association (THA). The survey is sent to all licensed hospitals in Texas. It collects data on finances, use, and other measures which hospitals are required by Texas law to report. Questions about immunization policies and practices are included each year. 

Immunization questions on the hospital survey fall into several categories including: 

  • Employee Immunization Policies 
  • Perinatal Hepatitis B Prevention 
  • Pertussis Immunization 
  • Participation in the Texas Vaccines for Children (TVFC) program 
  • Obtaining consent for the statewide immunization registry (ImmTrac2) at birth 

Methodology 

In the 2018 Annual Survey of Hospitals, the response rate for the survey was 97%, resulting in data from 599 hospitals. All data was self-reported by the hospitals. Analysis was also performed on a subset of 220 birthing hospitals. 

Results (View Full Report for more details) 

  • 95.3% of hospitals had an employee immunization policy. 
  • 83.2% of women were screened at delivery for Hepatitis B Surface Antigen. 
  • 67.9% of infants reportedly received the recommended first dose of Hepatitis B vaccine within 24 hours of birth. 
  • 80.1% had a written policy to provide new parents with immunization information before hospital discharge. 
  • 55.5% of birthing hospitals said they were registered as Texas Vaccines for Children providers. 
  • 91.8% of birthing hospitals offered new parents the chance to give consent for immunization registry participation, or request exclusion from the registry, during birth certification registration. 
  • 68.1% of hospitals that reported offering outpatient prenatal clinic services had a policy and standing orders to vaccinate all pregnant women with Tdap.

About the National Immunization Survey-Child (NIS-Child) 

The National Immunization Survey–Child (NIS-Child) is conducted annually by the Centers for Disease Control and Prevention (CDC) to assess immunization coverage (percent of the population vaccinated) among young children. 

The NIS is the only population-based survey to provide national, state, local area, and territorial estimates of vaccination coverage among children in the United States. This study collects data by administering telephone surveys to randomly selected households. To ensure the accuracy and precision of the vaccination coverage estimates, immunization data for surveyed children are also collected through a mail survey of their pediatricians, family physicians, and other health care providers. The parents and guardians of eligible children are asked during the telephone interview for consent to contact the children’s vaccination providers. Data are weighted to be representative of the population of children 24 months of age, and are adjusted for multiple phone lines, mixed telephone lines (i.e., landline and cellular), household nonresponse, and the exclusion of phoneless households. The survey also tracks progress towards Healthy People 2020 and Healthy People 2030 goals. 

CDC changed the way that NIS results are reported starting in 2019. In the past, results were reported for children 19-35 months of age at the time of the survey. Now, results for most vaccines are reported at 24 months of age by birth year. Exemptions to this are the hepatitis B birth dose and Rotavirus vaccines which are reported at younger ages because they are completed before 24 months. 

Coverage rates were reported for the U.S., Texas, and the selected areas of the City of Houston, Bexar County, El Paso County, and Dallas County.    

Survey Sample 

2020 NIS-Child data was collected from 2018 to 2020, resulting in a national sample size of 29,114 children born in 2017-2018 with adequate provider data. Additionally, these estimates reflect vaccinations that occurred mostly before the COVID-19 pandemic. For data collected in 2020, there was a low interview response rate (22.5%) and adequate provider data was available for only 54.2% of those with completed interviews. 

Vaccines Included 

The NIS collects information on the following vaccine series to assess the percent of children that are up to date with routinely recommended vaccinations: 

  • Diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP/DT/DTP) 
  • Poliovirus vaccine (Polio) 
  • Measles or Measles-Mumps-Rubella vaccine (MMR) 
  • Haemophilus influenzae type b vaccine (Hib) 
  • Hepatitis B vaccine (HepB) 
  • Varicella vaccine (Var) 
  • Pneumococcal conjugate vaccine (PCV) 
  • Hepatitis A vaccine (HepA) 
  • Rotavirus vaccine 
  • Influenza (Flu) 
  • 4:3:1:3*:3:1:4 series 
    • ≥4 doses of DTaP 
    • ≥3 doses of Polio 
    • ≥1 dose of MMR 
    • ≥3 doses of Hib (*3 or 4 doses depending on vaccine type) 
    • ≥3 doses of HepB 
    • ≥1 dose of Var 
    • ≥4 doses of PCV 

The 4:3:1:3*:3:1:4 series reflects vaccine coverage for seven key vaccines combined. It measures overall compliance with the recommendations of the Advisory Committee on Immunization Practices (ACIP) for young children.
